Logos and buttons

Buttons

Please note that simply adding a button does not license your work in any way. You have to clearly state which license you use. One way of doing that is making the link point to the license, and having an explicit statement "This work is licensed under the ... license" below the work.

AMYMADE's buttons

The following set of buttons were designed by AMYMADE with the support of the Free Software Foundation and represents our official recommendation:

These buttons are in the public domain. Which color you use is your choice; we suggest red for music, black for science and software, and yellow for everything else.

Small buttons

This is the cleanest set so far and it comes with a template.

Inkwina's icons

The svg versions CC-BY-SA.svg and Image:GNU_FDL.svg do not display well online. They where created using Inkscape, and the SVG hasn't been cleaned up. But the Blank button.svg can be used to generate more buttons. --Inkwina 15:01, 22 February 2007 (CET)

Other button styles

License Classification Icons by Terry Hancock

These are meant to be generic analogs to Creative Commons' "license deed" icons (The CC icons are subject to trademark. I intend these icons to be different enough to avoid any trademark dispute or confusion, but similar enough to facilitate communication). Unlike the CC icons, these do not map to particular detailed license modules, but rather indicate general classes of licenses.

So far, these are the only ones I could think of needing for free licenses, but I am interested in hearing suggestions for what additional requirements we ought to have icons for:

"Public Domain" or "No Requirements".

"Attribution" requirement.

"Copyleft" or "Share Alike" requirement.

"Source Code" requirement.

"No DRM/TPM" requirement.

"Production Copyleft" (a proposal for effective copyleft on hardware designs)

I also have some "non-free" icons for license comparison purposes, along with color-coded versions of the above (black="null", green="maximal individual freedom", blue="maximal maintenance of freedom", yellow="semi-free or free within a limited domain", red="not free at all"). I recommend these icons for use where free and non-free licenses will be compared with each other:

"Public Domain" (same as above)

"Attribution"

"Copyleft"

"Source Code"

"No DRM/TPM"

"Non-Commercial"

"Non-Derivative"

"All Rights Reserved"

Here are a set of icons representing the Four_freedoms:

Freedom #1: Use/Performance

Freedom #2: Understanding

Freedom #3: Copying and Distribution

Freedom #4: Derivatives

License description pages

For each license, we will try to create a description page. Here are some examples:

• Licenses/CC-BY-2.5 - Creative Commons CC-BY 2.5
• Licenses/CC-BY-SA-2.5 - Creative Commons CC-BY-SA 2.5
• Licenses/GNU GPL 2 - GNU General Public License 2
• Licenses/GNU FDL 1.2 - GNU Free Documentation License 1.2
• Public domain
